"Unfortunately I will not be able to be in Monte Carlo because of physical
problems," the Spanish star said on his Twitter feed on Thursday.

Monte Carlo kicks off the European clay-court season. Ferrer was the runner-up
two years ago.

The 31-year-old Ferrer, who led the ATP in match wins and titles last year,
has already appeared in four finals this season, including titles in Auckland
and Buenos Aires. He was a runner-up at the Miami Masters last month.
